As you probably know, any head gasket that will work on a regular 350 will work with the vortecs. Most people seem to have good luck with the 1094's. I personally don't feel comfortable using a gasket that thin on an undecked block and unsurfaced heads. Have you measured the deck height on your engine? If you decide on the 1094's, make sure it won't put your deck height under about .040. It shouldn't if you have a stock shortblock, but you need to check to make sure. GM still makes the .028 gaskets, BTW.
